6T40 Valve Body 2010-2017, remanufactured and ready to install. Fits the 6T40. Ships fast from the USA.
If your 2010-2017 Chevrolet Cruze, Sonic or Malibu is shifting harsh, slipping between gears, delaying engagement into drive, or has set a stored pressure or solenoid code, a worn 6T40 valve body is one of the most common reasons why. This is a remanufactured, bench-ready valve body covering 2010-2017 production, so you install a known-good hydraulic and electronic control unit instead of chasing a worn bore or a tired solenoid winding one part at a time.
The 6T40 is GM's lighter front-wheel-drive member of the 6T30/6T40/6T45 six-speed family, running behind the 1.4L turbo and 1.8L in the Cruze and Sonic and the 2.4L in some Malibu applications. Inside it, the valve body routes line pressure through precision bores and spool valves to apply each clutch and band, and it carries the shift and pressure-control solenoids the transmission computer uses to time every shift. Across 2010-2017, GM updated this casting more than once, and a worn or outdated unit shows up first in how the transmission shifts, not as a fluid leak or a noise.
Scan for codes and note which specific shifts are affected before ordering - our 6T40 valve body symptoms and testing guide walks through separating a hydraulic valve body fault from a solenoid-only problem, and 6T40 delayed engagement guide covers the cold-start engagement delay specifically if that is your complaint. 6T40 harsh shift causes and fix is the place to start if banging or flared shifts are the only symptom you have.
This valve body is built for the 6T40 as installed across 2010-2017 production. GM ran several casting, solenoid and pressure-switch revisions within that span, so match your connector count and casting marks against the photos before installing, or send your exact year and VIN so we can confirm the correct revision rather than guessing from the model year alone. The full Gen 2 casting is worth a look if your build falls right at a changeover year and you want to transfer your own solenoids and TEHCM instead.
Drop the pan and change the filter in the same job as the valve body swap so debris from the old unit does not circulate into the new one, torque the valve body bolts in GM's specified sequence rather than corner to corner, and refill with Dexron VI ATF only. Clear codes and run the TCM's adaptive relearn after the swap so the computer re-times clutch fill against the new unit instead of the one it adapted to over years of wear. If the car is a 2013-17 build, a 6T40 shift kit for 2013-17 firms up the same circuits this valve body controls, and a 6T40 sprag clutch is worth checking at the same time if your original complaint included a harsh reverse engagement rather than just forward shift quality.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It fits the 6T40 as used in 2010-2017 Chevrolet Cruze, Sonic and Malibu. GM ran several casting and connector revisions in that span, so match the photos against your unit or send your VIN to confirm.
Harsh or flared shifts, slipping between gears, a delayed engagement into drive on a cold start, torque converter clutch shudder, and limp mode with a stored solenoid or pressure code.
Remanufactured and bench-ready to install.
Dexron VI ATF.
Yes - clear codes and run the TCM's adaptive relearn so the computer re-times clutch fill against the new valve body.
On a 2013-17 build, a matching shift kit firms up the same circuits the valve body controls, and it's worth checking the sprag clutch if your complaint included harsh reverse engagement.
